Here's a little bookmarklet that tells you the average user age contibuting to the thread. November 25, 2004 1:29 PM   Subscribe

So I keep noticing thousands of new usernames in comment threads (which is awesome), and I got to wondering about how user age/contribution patterns were evolving on a threadwise level with the new users settling in. Being a non-statistician, I didn't care enough to perform a serious study, so I just threw together a little bookmarklet that tells you the average user age contributing to the page. It's totally worthless, but a bit of fun.

I just tried it in two diff threads (firefox, os x) and it told me the average age was 1222 or something like that.

dobbs: which threads?
posted by DrJohnEvans at 2:21 PM on November 25, 2004


Hm, it doesn't yet work for the MeFi front page when you're not logged in, because for top-secret reasons, user links are displayed completely differently then. Interesting.

Well this meta thread tells me the average age is 14872.

Can you make one that calculates IQ, too?

I'm just posting to further lower the average of this thread.

I'm just wondering where the age info comes from. There's no "birthday" or "age" box on the profile page i have.
posted by reflecked at 5:12 PM on November 25, 2004


It's 'age' as derived from your user number. The higher it is means the 'younger' the user (i.e. more recently joined).

In Safari it says the oldest user is 100,000; the youngest is 0 and the average is "NaN"

use the median, it is a better estimator than average (find that value that is > half of values in the list)

The bookmarklet thing sends fairies to the houses of all the thread contributors while they are asleep, and gives them a kiss. If the kiss is true and pure, a new fairy is born. That's how the average age is calculated

What John Shaft said.

This post is my contribution to skewing.

You probably guessed this isn't the first time I drove down an average.

The front page averages; interpret at your own risk:

MetaFilter: 12564 (new user privileges are just starting to kick in)
MetaTalk: 12085
Ask MetaFilter: 14260

I might figure out a median one at some point; that's a good idea. Sorry about Safari; I've no access to an appropriate development platform.

Unless is did the math wrong, which is quite likely, here is a median bookmarklet.

Nope, the only way to get older around here is to encourage others join the light side.

posted by wendell at 1:55 PM on November 26, 2004


not to digress to an earlier point which might be worth pursuing or anything: by default, your username owns you: you decide (sometimes a bit too spontaneously/haphazardly) what your username will be, and then you're indentured to it: you can't change it-- or lose your ranking, stats, etc. There must be some way to change this, some new approach, as the internet is becoming a life long activity, and the name one chooses-- or improvises-- when 17 may not be what you want at 30... is there anyway to create a new name, but keep your history? Or become a new user.. but with traces from your past 'life' still active. IS this not an opportunity to innovate? Any ideas?

Way to screw up the average, man. Now we'll never get to 10000.
posted by DrJohnEvans at 6:56 PM on November 26, 2004


DrJohnEvans, you're only the median if you give extra weight in the direction of users who have posted more than one comment. I made another version that calculates the average and the median with no extra weight for multiple comments.
